The WESOA series of workshops addresses challenges that arise from unique characteristics of service-oriented applications by focusing on principles, methodologies and tools that support the entire service-oriented software development lifecycle (SDLC). Topics of interest include software service development lifecycle methodologies, service-oriented enterprise architectures, service engineering for cloud computing environments, models, languages and methods for service-oriented analysis and design, and related topics.

Service-oriented applications play an important role in enterprise computing and more recently in the emerging field of cloud computing. While there is an agreement about the main principles, methodologies and tools for designing and developing such applications that support the development service-oriented applications are still the subject of intensive research. It is recognized that traditional software engineering approaches have significant limitations in the context of service-oriented computing and that there is a need for engineering methods to support the development of software services. Close collaboration between the research community and industry practitioners is essential to develop comprehensive engineering methodologies and tools that support the entire SDLC of service-oriented applications. 

WESOA complements ICSOC focusing on core software service engineering issues, as well as keeping pace with new developments that include research into methods for engineering of cloud services. Our aim is to facilitate exchange and evolution of ideas in service engineering research across multiple disciplines and to encourage participation of researchers and practitioners from academia and industry, avoiding disconnection between these groups. To promote collaboration the WESOA workshop has a highly interactive format with short technical sessions complemented by panel discussions. WESOA 2012 continues a successful series of ICSOC workshops. Over the past seven years, WESOA has demonstrated its relevance by attracting a large number of contributions and participants, and producing high-quality papers that were published by Springer in its LNCS series and in a special issue of the IJCSSE journal.
